Unable to stretch beam length

Issue description

After placing a beam in Archicad, you are unable to use the stretch command from the pet palette, instead the beam reverts to its original fixed length and cannot be adjusted to a new length.

Solution

The beam segments are set to fixed length rather than flexible length. When a beam segment is set to fixed length, it will maintain that exact length even when you try to stretch the beam.

1. Select the beam that cannot be stretched.
2. Right-click and choose Beam Selection Settings from the context menu.
3. In the Beam Settings dialog box, locate the Segment list at the top of the dialog.
4. Select the segment you want to modify from the list.
5. In the Structure panel below, click on the flexible icon instead of the fixed icon that is currently selected.
   
6. For each flexible segment, you can define the percentage of how much it will contribute to the overall stretching:
   • If you have multiple flexible segments, you can set different percentages for each segment
   • The total percentage of all flexible segments must equal 100%
7. Click OK to apply the changes.
8. Now select the beam again and use the Stretch command from the pet palette to adjust its length.
9. Click on the beam endpoint and drag to the desired new length.
